Claims.

The invention as. described herein, and illustrated in the accompanyingdrawings, consists of an oar actuating device, an object of which is toprovide means whereby the paddle of an oar may be moved in a directionopposite to that of its actuating means.

Another object of the invention is to provide means whereby aperson mayrow a boat in the direction in which he is facing.

A still further object of the invention is the provision of a rockingplate upon which an oar is pivotally mounted, an actuating handle forthe oar having independent connection' relative vto the oar andoperating means through which the oar is actuated..

Other features and advantages will become more readily apparent from thefollowing description and the accompanying illustrative drawing inwhich:

Figure 1 is a plan view of the invention shown mounted upon a boatgunwale,

Figure 2 is a sectional view `taken online. 2--2 of Figure 1, v

Figure 3 is a sectional detail of a pivot member taken on line 3-3 ofFigure 1, Y

Figure 4 is a bottom plan view of an oar supporting means,

Figure 5 is an enlarged sectional elevational view thereof,

Figure 6 is a detail perspective view of anoar pivot member, and jFigure 7 is a detail perspective member.

While one embodiment of the invention is illustrate-cl in the abovereferred to drawings, it is to be understood that they are merely forthe purpose of illustration and that various changes in construction maybe resorted to in the course cf manufacture in order that the inventionmay view of a rocker Ybeutilized tothe best advantage according to.circumstances which may arise,-without' in any 'way departing from thespirit;and intention of the device, which is to be limited only inaccordance with the appended claims. And while there is stated theprimary eld of utility of the invention it remains obvious that it maybe employed in any other capacity wherein it may be found applicable.

In the accompanying drawings, and in the following specication, the samereference characters are used to designate the same parts and elementsthroughout and in which l0 refers to the invention in its entirety andIl indicates the gunwale of a boat l2 in which is pivotally supported anoar lock l2' on which is reciprocatingly .I

supported a rocker member i3 by means of a bolt pin I1 having a reducedend I8 upon which is pivotally mounted the outer end I9 of an oarcontrol lever 20.

; Mounted upon the opposite sides 2| and 22 of the plate l5 are a pairof bearings23and 24 for pulleys 25 and 26 over whichA operates a cable21 having a ring or upper stop member 28 set. in its upper side 29, andan oppositely located ring or lower stop member 30l set in itsunder-half 31. The lever 20 projects through the ring 28 whereby whenthe handle k32 of the lever is reciprocated back and forth when-rowingthe same motion will be transferred to thecable 21.

Mounted upon the plate l5 is an oar 33, the shankV 34 of which has acollar 35 thereon, which collaris provided/with a right-angularlydisposed bearing-'3E adapted to engage and pivot upon the pin I1'. Theflaring jaws 31 and 38 of the bearingSB may be of suiiicient springtension to hold to the pin l1, or if found necessarythey may beconnected by a hook (not shown). The end 39 of shank 34 projects throughthe ring 30 of the lower cable portion 3| whereby upon movement forwardand back thereof the oar will be actuated but in a direction opposite tothe movement of the actuating lever 2l),Y thus the boat l-2 will bemoved in a direction in which .the oarsman is .ffacing.- A pin 40extends through collar 35 and `into shank 34 inV order to keepY thepaddle 4| properly feathered. f Provided on the underside 42 of plate l5is a Vg-shaped restY 43 adapted to be seated in the recess 44 formed inthe apex of the triangular 'supportfdd mounted-on the gunwale of theboat `whereby the -p1ate;'l5 is 'held to up and down vrocking motiononly during the rowing operation. VThere is alsoiprovided a V-stop 46located on said side 42 of the plate I5, the purpose of which is to beengaged over the upper edge 41 of member 44 to hold the plate l5 againstpivotal movement when the oars are at rest on the boat. An angle-iron 48is attached to plate l5 adjacent the said cable 21, the flanges 49 and49 of which will limit down pressure upon the cable by the members 20and 34. The said flanges are provided with a longitudinal slot 50 forthe shank 34 of the oar.

From the above description it will appear obvious that the outfitdescribed will have free universal movement as the plate may rock up andlt is thought that persons skilled in the a't to which the inventionrelates will be able obtain a clear understanding of lthe inventionafter considering the description in connection with the drawings.Therefore, ia more lengthy description is regarded as unnecessary. v
